Engineers at GE China R&D Center are still working on 3D printing technology.
Just before that, they just successfully "printed" out the important parts of the aero engine with a 3D printer. Compared to traditional manufacturing, this technology will reduce the cost of the part by 30% and the manufacturing cycle by 40%. It’s too late to celebrate this gratifying result, and they have rushed to a new journey. Little known is that they have been "secret" in developing 3D printing technology for ten years.
An engineer named Jim Smith created the world's first 3D printed kayaking through 3D printing technology and successfully launched it.
This "kayak" was built by him for 42 days using a homemade large 3D printer. It is 5 meters long and is assembled from 28 pieces of colored ABS plastic. Each part is made of a 3D printer and then bolted together.
The manufacturing process seems to be simple, but it takes a lot of effort. It took Smith nearly six years from the start of planning to the completion of the manufacturing process, and the final adjustment before the launch took 40 days. The finished product is 5.08 meters long and 0.52 meters wide, with a total weight of 29.29 kilograms. The ABS part weighs 26.48 kilograms, the brass threaded parts weigh 0.86 kilograms, the bolts weigh 2.068 kilograms, and the total cost is only $500.
3D printing technology has become increasingly mature, and it is not impossible for people to use it to build houses, build cars, and even more.
On June 22, 2015, the state-owned Russian technology group company built a prototype of a drone with 3D printing technology, weighing 3.8 kilograms, with a wingspan of 2.4 meters, a flying speed of 90 to 100 kilometers per hour, and an endurance of 1 to 1.5. hour.
Company spokesperson Vladimir Kutahof said that the company achieved a leap from concept to prototype in two and a half months. The actual production took only 31 hours and the manufacturing cost was less than 200,000 rubles (about 3,700 US dollars).
